Don't have a video to link too but if you're going sterile water route wipe down your area with at least 70% isopropanol if you don't have the actual wipes, wash hands before touching your stuff and never forget to wipe down the vial rubber port with iso also
There's a yt video of Peter magic from janoshik saying the risk between BAC and sterile water is almost the same although I got downvoted to death on Reddit for simply saying that. My poor karma 😭
